First you can check what binaries listen what port. As root use command:
netstat -ap or probably netstat -ap | grep LISTEN P.S. I'm not sure if switch -p works on Debian. It works on Slackware 7.0 - probably it should work on Debian. >>>>> "WL" == William Leese <[EMAIL PROTECTED]> writes: WL> When running nmap -sT and -sU on my static IP# i get the following WL> 1/udp open tcpmux WL> 7/udp open echo WL> 9/udp open discard WL> 69/udp open tftp WL> 161/udp open snmp WL> 162/udp open snmptrap WL> 513/udp open who WL> 635/udp open mount WL> 640/udp open pcnfs WL> 641/udp open unknown WL> 700/udp open unknown WL> 31337/udp open BackOrifice WL> 32770/udp open sometimes-rpc4 WL> 32771/udp open sometimes-rpc6 WL> 32772/udp open sometimes-rpc8 WL> 32773/udp open sometimes-rpc10 WL> 32774/udp open sometimes-rpc12 WL> 54321/udp open bo2k WL> Port State Service WL> 1/tcp open tcpmux WL> 11/tcp open systat WL> 15/tcp open netstat WL> 79/tcp open finger WL> 111/tcp open sunrpc WL> 119/tcp open nntp WL> 143/tcp open imap2 WL> 540/tcp open uucp WL> 635/tcp open unknown WL> 1080/tcp open socks WL> 1524/tcp open ingreslock WL> 2000/tcp open callbook WL> 2401/tcp open cvspserver WL> 6667/tcp open irc WL> 12345/tcp open NetBus WL> 12346/tcp open NetBus WL> 31337/tcp open Elite WL> 32771/tcp open sometimes-rpc5 WL> 32772/tcp open sometimes-rpc7 WL> 32773/tcp open sometimes-rpc9 WL> 32774/tcp open sometimes-rpc11 WL> 54320/tcp open bo2k WL> to me, this doesn't look good. half of these services i know i do not have WL> installed, neither do they show up on a ps aux.
